Oleaginous compound.



UNITED CUSHING ADAMS, OF BELLOWVS FALLS, VERMONT.

OLEAGINOUS COM POUND.

SPECIFICATION forming part of Letters Patent No. 709,291, datedSeptember 16, 1902.

Application filed June '7, 1901. Serial No. 63,591. (No specimens.)

To all, whom it may concern:

Be it known that I, OUSHING ADAMS, a citizen of the United States,residing at Bellows Falls, in the county of Windham and State ofVermont, have invented certain new and useful Improvements in OleaginousCompounds and Processes of Producing Same, of which the following is aspecification.

It is a well-known fact that many processes [0 have been adopted forsolidifying vegetable oils for commercial products. An example of thesemethods is that of thickening'cottonseed oil by the use of stearin;There are,

however, many disadvantages connected with the methods which are atpresent commercially used, both as to the want of stability of theproduct as well as the excessive cost of the same. 1

This invention or discovery has for its ob- 2o ject to produce a novelsolidified or semithe appearance of fine lard, and which by practicaltests has been found to be an excellent substitute for the same, thisresult being based on a discovery which 1 have made relative to the useof certain casein compositions with Vegetable oils.

0 In carrying my invention or discovery for thickening and solidifyingvegetable oils into efiect I gradually add, with constant agitation, analkaline or other casein solution mixed with water to the oil to bethickened 3 5 and solidified. v

To enable those skilled in the art to practice my invention ordiscovery, the following is an example of the manner in which the same imay be carried into effect: To one hundred parts, by Weight, of drycommercial casein I add fifteen parts, by weight, of a suitable alkali,preferably bicarbonate of soda, and six hundred parts, by weight, ofwater. These ingredients should be made into a perfeet solution byheating the same in a jacket kettle or hot-Water bath. To the solutionis then gradually added, with constant agitation, by stirring orotherwise, six thousand parts of vegetable oil, preferably cotton-seedoil, and the agitation is continued until the product assumes a smoothwhite appearance resembling, for example, that of cold lard.

In the practice of the above-described process a partial saponificationof the product results from the chemical union of the alkali and oil;but if it be desirable to secure a partially or wholly solidified masswithout the partial saponification resulting from the process justdescribed I carefully neutralize the free alkali or very slightlyacidulate the casein solution by adding thereto a weak solution ofacetic acid, formic aldehyde, or other suitable acid or acid salt, thisbeing done before the vegetable oil is added to the mixture of thecasein solution and water, and when the vegetable oil in about theproportions heretofore stated has been added to this neutralized orslightly acidulated solution in the manner hereinbefore described aperfect emulsion which closely resembles cold lard and which is uniformand stable in its composition and appearance is produced. The weaksolution of formic aldehyde above referred to would be about five percent. to ninetyrfive per cent. of water.

By following out the process hereinbefore described I am enabled toproduce a solidified or semisolidified product suitable for manywell-known uses for which lard is now employed for cooking purposes,which is practically odorless and which has very much less of adisagreeable flavor than that characteristic of cotton-seed oil and someother vegetable oils.

I do not wish to be understood as limiting my invention or discovery tothe use of the exact proportions of the ingredients hereinbefore statedor to the use of bicarbonate of soda as an alkali in forming the caseinsolution, although bicarbonate of soda as an alkali is preferred; nor doI wish to be understood as limiting the invention or discovery to theuse of cotton-seed oil for the production of my solidified orsemisolidified oil, as other vegetable oils might be used instead ofcotton-seed oil, although, so far as I now know, cotton-seed oil is thebest vegetable oil, cost being considered, for use for the purposeindicated.

Having thus described my invention or discovery, I claim and desire tosecure by Letters Patent- 1. The herein-described oleaginous compound orcomposition of matter, consisting of approximately seven parts of asolution of casein and sixty parts of a vegetable oil, thoroughly mixedand incorporated together, substantially as set forth.

5 2. The herein-described oleaginous compound or composition of matter,consisting of approximately seven parts of a solution of casein andsixty parts of cotton-seed oil, thoroughly mixed and incorporatedtogether,

'10 substantially as set forth.

3. The herein-described process for thickening or solidifying avegetable oil to produce an oleaginous compound, such process consistingin gradually adding, with constant I 5 agitation, to about sixty partsof the oil to be thickened or solidified, about seven parts of asolution of casein, substantially as set forth.

4. The herein-described process for thickening or solidifyingcotton-seed oil to produce an oleaginous compound, such process con- 20sisting in gradually adding, With constant agitation, to about sixtyparts of the oil to be thickened or solidified, about seven parts of asolution of casein, substantially as set forth.

In testimony whereof I affix my signature 25 in presence of twowitnesses.
